Question: Overclocking in XP vs. 2000

[EtOH]

I noticed something odd during beta 2 of XP and thought I would see if anyone else noticed it as well. Bear with me here.

Before XP I was running 2000 pro w/ SP2, non-ACPI setup. My AXIA would only overclock from 1.00 to 1.33 GHz at default voltage. Anything higher than that would lock up solid within 10 minutes, no matter what voltage was used.

Along comes XP Beta 2 and I decided to try to clock it higher. 1.4 GHz stable as a rock at default voltage under a non-ACPI setup, haven't tried higher than that.

After beta 2 I went back to 2000 Pro for a little while. Once again 1.33 GHz was as high as it would go for me. Voltage didn't help.

I am now running devilsown XP final (don't ask where I got it, just do some digging), Set it up to 1.4 GHz and all is running like a champ again.

So the final tally is:

Win 2000 Pro
Non-ACPI
1.33 (10 x 133) @ Default Voltage - ROCK STABLE
1.40 (10.5 x 133) @ Any Voltage - UNSTABLE

Win XP Pro
Non-ACPI
1.33 (10 x 133) @ Deafult Voltage - ROCK STABLE
1.40 (10.5 x 133) @ Default Voltage - ROCK STABLE
1.46 (11 x 133) @ Any Voltage - UNTESTED

Has anyone else noticed an increase in Overclocking performance under XP compared to 98?

I never knew...

I've noticed the opposite actually. I had to tune down my overclock while running XP. I got random reboots after formatting and installing it. Went from 1.62 to 1.46. I just defaulted my fsb back to 133...i didn't make any stops in the middle so I haven't really seen the limit of my o/c in XP, but it definately wasn't as stable as the same setup i had running 98 SE.
